I got a new machine with i7 4770k and gefore gtx660. I installed windows and then installed Ubuntu 13.04. In the installation everything went well, after the installation I again boot from the USB and choose try ubuntu, and installed boot-repair because windows automatically boot with no option for ubuntu.

After I repaired the boot, I restarted and got into grub, when I chose Ubuntu I got message saying I'm running on low graphics mode and when I pressed ok the screen turned off. I couldn't do anything so I restarted and after reading this post: My computer boots to a black screen, what options do I have to fix it?

I got into recovery, selected dpkg and repaired packages. Then I rebooted, and tried to press 'e' and change quiet splash to no splash and nomodeset but unfortunately both of them didn't work, and not the screen didn't get turned off, but I just saw a blank screen.

So I rebooted again, entered the recovery, and this time I went to the root shell, and tried to install nvidia drivers from this guide here: http://www.howopensource.com/2012/10/install-nvidia-geforce-driver-in-ubuntu-12-10-12-04-using-ppa/

I rebooted and got the same black screen again (the screen didn't go off, just saw a blank screen).

In the grub I see that the kernel is 3.8.0-25.

I also checked that the usb files are not corrupted using the check CD from the ubuntu installation screen.

I'm really frustrated, I don't know what else can I do.

(If someone also knows how can I connect to wifi using the root shell it will be very appreciated, because when I choose the 'enable networking' it again booting me to a black screen.

Thanks

Edit

After digging more, I again boot with nomodeset and saw where is it failing, this is the lines I saw:

* Starting Reload cups, upon starting avahi-daemon to make sure remote queues are populated [OK]

* Starting Reload cups, upon starting avahi-daemon to make sure remote queues are populated [fail]

I searched for it in google and this is the closest result I got: http://ubuntuforums.org/showthread.php?t=2144261

i didn't find any way to solve it in the internet, from what I understand this is a problem with 13.04. If someone knows how to fix it I will be very grateful.

Thanks

Edit 2 - 23.6.13

As Mitch suggested, I disabled the avahi-daemon, and when I boot in nomodeset I get the following error:

What else can be the problem?
